krb5-admin-server: An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16
CVE-2018-5710 is fixed in 20 products on 1 platform, first by krb5-admin-server 1.16-2ubuntu0.1, released March 6, 2018. It is not reported as exploited. Patch Radar priority: Routine.
An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. The pre-defined function "strlen" is getting a "NULL" string as a parameter value in plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in the Key Distribution Center (KDC), which allows remote authenticated users to cause a denial of service (NULL pointer dereference) via a modified kadmin client.
